1. Small vacuum line to BOV...could also T this for boost controller
2. Vacuum line to charcoal canister
3. Bigger vacuum line to cold pipe

I checked the service manual but it's somewhat complicated due to dashed marks under the cold pipe. It almost looks like there is supposed to be 3 smaller vacuum hoses coming from the intake manifold...am i missing one? Anyone with an S15 who could chime in would be great...thanks guys

Here's the FSM diagram for the vacuum hoses...

2 questions was it correct and would this work for an s14 sr20det. Im having a little trouble with the vacuum diagrams that im finding, they are all a little too confusing to me.

Hey there. I am doing my swap at the moment too. I capped both of my bottom 2 little pipes because I didn't need them. After taking out a lot of the emission controls you really don't need much. I believe the bigger pipe is for your Idle Air Control Valve which you need to run to your coldpipe.

I believe you can tee everything together that is positive pressure and tee everything that is negative pressure. keep them separate to make them work properly. If I am wrong, then someone correct me please.

Hope this helps
